Delgado was hit by a car while riding her bike in 2010. The crash left her in a coma.

Returning to the Pig last year seemed like a long shot.

"Most of my doctors after my injury didn't expect me to go back into medicine, didn't know if I was going to be able to run again," Delgado said.

But she proved them wrong.

"Running the Pig last year was just kind of about coming back," Delgado said.

She came back, in amazing form, leading through much of the race.

"To try to give other people hope as well, people who've been through similar situations to say, you know, after something like that happens, just never give up, never give up, because you can always surprise yourself with what you can end up doing," Delgado said.

She wasn't sure she'd run the full pig this year because she was running the Boston Marathon. Delgado crossed the finish line about an hour before the blasts.

"It was kind of frantic. There were some people kind of running around, police cars flying by," Delgado said. "Walking back to our hotel, and then turned on the TV and actually saw what they explosion was, and it was just terrible."

As people run the pig, with Boston on their minds, Delgado is living proof that sometimes, with help, you can come back stronger than before.

"I had a lot of support, which is definitely very helpful to me. My husband was amazing, my parents were with me every day in the hospital, and so many friends who came and visited me," she said. "Prayer was a big thing for us as well - it really was. Just having faith that things will get better, it's tough right now, but things will get better."

As for this year, Delgado isn't making any predictions.

"I'm just gonna go out and try to run a smart race. The best I can, try to run my pace."
